1,which,后面缺主語.
2,D,這句中前面是虛擬語氣,只是省略了if,選D；
3,D,call up號召.call in叫（某人）進來；來訪；找[請]來；用電話通知.call back回喊；叫（某人）回來[去]；回電話；記起（某事）call for去接(某人)；去取(某物)；需要；要求.第二個哪里省略了if ，Had the coaches discovered his potential they would not have laid off the player指什么意思看來閣下應該是高二的學生，如果沒猜錯的話。Had the coaches discovered his potential last year,they ( ) off the player，原句應該是if the coaches had discovered his potential last year,the would not have laid off player,在這樣的虛擬語句中，可以把had提前，if省略，你們應該馬上就會學到。這句法醫(yī)過來的意思就是：如過當初教練發(fā)現(xiàn)了他的潛能，那么他們就不會解雇他。這里是虛擬語氣。還有道不清楚I‘ve never been to Beijing，but it’s the place （）.Awhere I'd like to visit BI most want to visit Cthat I want to it most 這是不是應該選擇C額，這道題我也有點暈了，畢竟好久沒有好好學語法了。但A是一定錯的，visit后面缺成分，C也是錯的，如果沒有it的話就是對的，所以應該算B，B可以這樣認為，but it’s the place（which）I most want to visit
